x86: Rename trap_no to trap_nr in thread_struct
There are precedences of trap number being referred to as trap_nr. However thread struct refers trap number as trap_no. Change it to trap_nr. Also use enum instead of left-over literals for trap values. This is pure cleanup, no functional change intended.
